This paper introduces three methodological advances to study the optimal design of static and dynamic markets. First, we apply a mechanism design approach to characterize all incentive-compatible market equilibria. Second, we conduct a normative analysis, i.e. we evaluate alternative competition...

Theoretical IO models of horizontal mergers and acquisitions make the critical assumption of efficiency gains.Without efficiency gains, these models predict either that mergers are not profitable or that mergers are welfare reducing.A problem here is the empirical observation that on average...

This paper shows that cross-border mergers are more likely to occur in industries which serve multiple segmented markets rather than a single integrated market, given that cost functions are strictly convex. The product price rises in the market where an acquisition is made but falls in the...

Abstract: Pricing pressure indices have recently been proposed as alternative screening devices for horizontal mergers involving differentiated products. We extend the concept of Upward Pricing Pressure (UPP) proposed by Farrell and Shapiro (2010) to two-sided markets. Examples of such markets...

We compare different methods to assess unilateral merger effects in a two-sided market by applying them to a hypothetical merger in the Dutch newspaper industry. For this, we first specify and estimate a structural model of demand for differentiated products on both the readership and the...

We propose a methodology for estimating the competition effects from entry when firms sell differentiated products. We first derive precise conditions under which Bres- nahan and Reiss'entry threshold ratios (ETRs) can be used to test for the presence and to measure the magnitude of competition...

This paper provides an analysis of the European Commission (EC) decisions on state aid control using data on 550 state aid cases approved by the EC between 1998 and 2009. More specifically, we measure the determinants of the duration of state aid, total budget of state aid and daily budget of...

We study the optimal design of liability schemes (at the corporate or individual level) when the objective is to deter socially harmful corporate behavior without discouraging productivity enhancements. We assume that firms face agency problems between shareholders and managers (moral hazard)...

This paper tests whether the transition from the old Economic Competition Act, which was based on the so-called “abuse system”, to the new Competition Act, which was based on “prohibition system”, in the Netherlands had an impact on the price-cost margins in manufacturing industries...

The main feature of the penalty schemes described in current sentencing guidelines is that the fine is based on the accumulated gains from cartel or price-fixing activities for the firm.These gains are usually difficult to estimate, but they can be approximated by a fraction of the turnover.The...
